ASoC: fsl_xcvr: Revert fix missing lock in fsl_xcvr_mode_put()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0886dc6326c3cc596799c4340d342898301cf52a, 29b2fbe3498da3681a01b34e4a2259f8a1b89448, 30ffcad5edb56947dccc26f6816ab7a55b21a711.

Low priority for now. Upgrade to Linux Linux 0886dc6326c3cc596799c4340d342898301cf52a, 29b2fbe3498da3681a01b34e4a2259f8a1b89448, 30ffcad5edb56947dccc26f6816ab7a55b21a711 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: fsl_xcvr: Revert fix missing lock in fsl_xcvr_mode_put() This reverts commit f51424872760 ("ASoC: fsl_xcvr: fix missing lock in fsl_xcvr_mode_put()"). The original patch attempted to acquire the card->controls_rwsem lock in fsl_xcvr_mode_put(). However, this function is called from the upper ALSA core function snd_ctl_elem_write(), which already holds the write lock on controls_rwsem for the whole put operation. So there is no need to simply hold the lock for fsl_xcvr_activate_ctl() again. Acquiring the read lock while holding the write lock in the same thread results in a deadlock and a hung task, as reported by Alexander Stein.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
